This medicinal product is for diagnostic use only.

Iopamiro belongs to a group of medicines called iodinated X-ray contrast media.

Iopamiro is authorized as a radiological contrast medium for the following indications:

• myelography (visualization of the spinal cord),
• arteriography (visualization of arteries),
• angiocardiography (visualization of the heart's blood vessels),
• phlebography (visualization of veins),
• digital subtraction angiography (visualization of blood vessels),
• computed tomography (CT) (obtaining images of sections or regions of the body),
• intravenous urography (visualization of the urinary tract) and
• arthrography (visualization of joints).

2. What you need to know before you use Iopamiro

Do not use Iopamiro

• if you are allergic to the active substance or to any of the other ingredients of this medicinal product (listed in section 6).
• if you have clinical hyperthyroidism (your thyroid gland produces too much thyroid hormone).
• if you have a history of severe immediate or delayed skin reaction to iopamidol injection.

Warnings and precautions

Consult your doctor or pharmacist before starting treatment with Iopamiro. Be especially careful if:

• You have experienced any reaction during previous injection of an iodinated contrast medium.
• You have a history of asthma.
• You have renal insufficiency, diabetes mellitus, or multiple myeloma.
• You have heart failure, coronary insufficiency, or other heart disease.
• You have any cardiovascular disease.
• You suffer from homocystinuria (a hereditary disease in which the body is unable to fully metabolize the amino acid methionine).
• You have liver insufficiency.
• You suffer from any nervous system disease, such as epilepsy, stroke, pheochromocytoma (excessive production of hormones that causes severe hypertension), myasthenia gravis (an autoimmune disease that affects muscles), or other autoimmune diseases.
• You have had thyroid dysfunction.
• You are in a state of excitement, anxiety, and intense pain, as this may increase the risk of adverse reactions or their intensity.
• You have any bone marrow disease (multiple myeloma or Waldenström's macroglobulinemia).
• You have had recent intracranial hemorrhage or epilepsy.
• You have cerebral edema or a brain tumor.
• You have significantly deteriorated health status.
• You have developed a severe skin rash, desquamation, blisters, and/or ulcers in the mouth after taking Iopamiro or other iodinated contrast media.

Be especially careful with Iopamiro:

Severe skin reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and acute generalized exanthematous pustulosis (AGEP), have been reported with the use of Iopamiro.

Seek medical attention immediately if you experience any symptoms related to these severe skin reactions described in section 4.

You may experience a short-term brain disorder, called encephalopathy, during or shortly after the imaging procedure. Inform your doctor immediately if you notice any symptoms related to this condition, described in section 4.

You should inform your radiologist if you are an alcoholic or drug addict.

Special care should be taken when administering to children under one year of age and to elderly patients. These groups may be susceptible to adverse reactions.

Inform your doctor if you have had thyroid function tests previously.

Thyroid disorders have been observed after iopamidol administration. Special attention should be paid to newborns, including those whose mother received iopamidol during pregnancy, and premature infants. Doctors may check the thyroid function of the child.

Consult your doctor, even if any of the above circumstances have occurred to you at any time.

Inform your doctor if you are going to have a thyroid function test or receive radioactive iodine treatment soon.

High concentrations of contrast media in serum and urine may interfere with the analysis of bilirubin, proteins, and inorganic substances (iron, copper, calcium, and phosphates). It is recommended that these determinations not be performed in the first 24 hours after the examination.

Using Iopamiro with other medicines

Inform your doctor or pharmacist that you are using, have recently used, or may need to use any other medicines.

Anticonvulsant therapy should be maintained before and after myelographic procedures in patients with a known seizure disorder.

Certain medicines may interact with Iopamiro; in these cases, it may be necessary to change the dose or discontinue treatment with one of the medicines. It is especially important that you inform your doctor if you are using any of the following medicines:

• Biguanides (metformin) (medicines used to treat some forms of diabetes mellitus)
• Neuroleptics (medicines commonly used to treat psychosis)
• Analgesics (medicines that relieve or eliminate pain)
• Anti-emetics (medicines that prevent vomiting or nausea)
• Antihistamines (medicines for the treatment of allergic rhinitis or dermatitis)
• Phenothiazine sedatives (tranquilizing medicines)
• Betablockers (drugs used to treat hypertension)
• Interleukin-2 (a medicine that regulates the immune response)
• Oral cholecystographic contrast media (for diagnostic use)
• Diuretics (medicines that increase urine production)
• Radioactive medicines (for diagnostic and therapeutic use)

Consult your doctor if you have any doubts.

Using Iopamiro with food and drink

Any alteration of the hydroelectrolytic balance should be corrected before the administration of the contrast medium.

Before the test, do not reduce the amount of water you normally drink, especially if you are in any of the following situations:

• Severe renal insufficiency
• Severe liver insufficiency
• Severe heart failure
• Multiple myeloma (bone marrow disease)
• Diabetes mellitus
• Blood disease
• Increased or decreased urine production
• Deterioration of health status
• Elderly patients

Fluid intake should also not be reduced in infants or young children.

You can maintain a normal diet until two hours before the examination. During the two hours prior to the study, you should abstain from eating.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Pregnancy

X-ray examinations in pregnant women should only be performed if the doctor considers it absolutely necessary or when the benefit to the mother outweighs the risk to the fetus.

Breastfeeding

Iodinated contrast media are excreted into breast milk in very small amounts. However, as a precautionary measure, breastfeeding should be suspended for at least 24 hours after the administration of the contrast medium.

Driving and using machines

No effects on the ability to drive and use machines have been observed.

Iopamiro contains sodium

This medicinal product contains less than 1 mmol (23 mg) of sodium per dose, so it is essentially "sodium-free".

3. How to use Iopamiro

Follow the instructions for administration of this medicine exactly as prescribed by your doctor. If you are unsure, consult your doctor or pharmacist again.

Iopamiro will be administered to you by a doctor or nurse in a hospital or diagnostic clinic.

Iopamiro must be administered into a vein or artery, into the spinal column, or into a joint.

You must be well-hydrated before receiving Iopamiro.

After administration of the contrast medium, you should remain under observation for at least 30 minutes, as most adverse reactions occur during this time. However, delayed reactions may occur.

The dose depends on the part of the body to be examined and usually ranges from 5 to 250 ml.

Your doctor may decide to vary this dose or repeat it if necessary.

The dose used in children also depends on age and body weight.

If you use more Iopamiro than you should

You should know that the hospital or clinic area where Iopamiro will be administered is equipped to treat any reaction caused by an overdose.

In case of overdose, allergic reactions, respiratory symptoms, cardiovascular disorders, convulsions, or tetanic crises (muscle stiffness) may occur.

Treatment of overdose should be aimed at ensuring support of vital functions and rapid establishment of symptomatic therapy.

If necessary, hemodialysis can be used to remove Iopamiro from your body.

In case of overdose or accidental ingestion, consult the Toxicology Information Service. Telephone 91 562 04 20, indicating the medicine and the amount ingested.

If you have any further questions about the use of this product, ask your doctor or pharmacist.

4. Possible Adverse Effects

Like all medicines, Iopamiro can cause adverse effects, although not all people suffer from them.

The adverse effects that you may experience after administration of a contrast medium are usually mild to moderate and tend to last for a short time.

However, as with other contrast media, in some cases, serious reactions occur, which can even be life-threatening, requiring rapid and effective treatment.

If you notice any of the following symptoms, inform your radiologist or X-ray personnel immediately, as these may be signs of an allergic reaction or shock. The examination should be interrupted and you may need treatment. The symptoms are:

• Swelling of the face and throat (angioedema).
• Tearful or itchy eyes (conjunctivitis), cough, itching, runny nose or nasal congestion, sneezing, hives.
• Severe drop in blood pressure, increased heart rate (tachycardia).
• Difficulty breathing, nausea, feeling of suffocation (allergic reactions).
• Agitation, blue lips, blue or pale face, cold sweats, loss of consciousness.
• Headache, dizziness.
• The drop in blood pressure may also be related to a decrease in heart rate (bradycardia), from which an increase in heart rate (tachycardia) usually develops.

These reactions can occur delayed and independent of the administered dose and method of administration.

Go to the doctor immediately if you notice any of the following symptoms:

• Reddish patches, without volume, circular or target-shaped on the trunk, often with central blisters, skin peeling, sores in the mouth, throat, nose, genitals, and eyes. These severe skin rashes can be preceded by fever and flu-like symptoms (Stevens-Johnson syndrome, toxic epidermal necrolysis).
• A generalized scaly red rash, with lumps under the skin and blisters, accompanied by fever. The symptoms usually appear at the start of treatment (acute generalized exanthematous pustulosis).

The frequency of occurrence of these adverse effects is unknown.
